F astened to the shaft or trunnion portion 18 of the roller 5 is the plate 19.-- it will be clear that on the movement of the said plate 19 the roller 5 will be moved a similar extent.-

Pivoted to and rising from the plate 19 at opposite sides of the center of movement thereof and of the roller 5 are pins 20 and 21 adapted to be alternately engaged by the armature 9, and when a pin is thus engaged on the movement of the downward armature, it is thrust down to rock the plate 19 and therefore the roller 5. The forwardly projecting portion of the plate 17 hasat its outer end enlarged perforations to receive the free portions of the pins 20 and 21 and to permit lateral movement of said pins.

In Fig. 2 the roller 5 is shown as being in one of its two positions, for examplethe on or operative position, the stop associated therewith being also on, the pin 21 being under the armature 9, so that when the magnet 6 is energized the armature is drawn down to thrust the pin or rod 21 downwa d to thereby impart a corresponding movement to the right branch of the plate 19 and therefore swing the roller 5 from the on to the off position. At the same time the pin or rod 20 is thrust upward as shown in Fig. 3 in position to be engaged by the armature 9 when the latter has been laterally moved as will hereinafter appear. Connected loosely to theplate 19 approximately centrally of the points of connection therewith of the two pins 20 and 21 is the spring 23 which extends upward through a notch 24 in the stud or projection 25 extending forward from the block 3 and also through an enlarged hole in the plate '5,

being continued upwardly from the plate and projecting freely through a perforation 26 at or near the free end of the armature 9, said spring constituting one of several ways for efi'ectingthe lateral movement of the armature 9 or equivalent actuator. On the denergization of the "magnet 6 by the opening of the circuit thereof, the spring 27 promptly returns the armature 9 toits initial upward position as shown in Fig. 1. It will be assumed that the parts are in the positions shown in Fig. 2 and that the mag net 6 has been. energized. As already set forth this results in the thrusting downward of the pin 21 by the armature 9, thereby swinging over the plate 19 and roller from the positions shown in Fig. 2 to those of Fig. 8. As the roller 5 oscillates in the manner in question the spring 23 is bowed or tensioned, so that when the magnet 6 is deenergized and its armature 9 elevated by the spring 27, said armature 9 will be moved laterally by the spring 23 over the top of the pin 20 as shown in ltig. t. if when the parts are in the position shown in Fig. i, the is ei'iergized, the pin 20 will be thrust down and the roller 5 through the described parts moved from oil to on and in the last'mentioned operation the action already described will be exactly reversed.

hat I claim is:

1. The combination of an oscillatory member, an actuator for operating said oscillatory member, and means for moving the actuator laterally into position to apply its effect to said actuator alternately at opposite sides of the center of oscillation thereof.

2. The combination of an oscillatory member, an actuator for operating said oscillatory member, and spring means for moving the actuator laterally into position to apply its effect tosaid actuator alternately at opposite sides of the center of oscillation thereof. v

3. The combination of an oscillatory member, pins connected with said oscillatory member at opposite sides of its center of movement, an actuator, and means for moving the actuator laterally into position to engage the pins in alternation.

e. The combination of an oscillatory memher, an actuator for oscillating said oscil latory member, and spring means tensioned by the oscillatory member on its movement for moving the actuator laterally into position to apply its effect to the oscillatory member lternately at opposite sides of the center of oscillation thereof.

The combination of an oscillatory member, pins connected with the oscillatory 7 member at opposite sides of its center of movement, a swinging actuator cooperative with the pins, a spring connected with the oscillatory member approximately centrally between the points at which the pins are connected therewith, the spring acting against the actuator to shift the same alter: nately in opposite directions laterally to position it'for successively engaging the pins and the spring being tensioned by the oscillatory member on the movement thereof.

6. The combination of an oscillatory member, an electrically governed member provided with a movable part, said movable part being positioned to oscillate said oscillatory mcn'iber. and means for moving said movable part laterally and into position to alternately apply its effect to said oscillatory member at opposite sides of the center of oscillation thereof.

'7. The combination of an oscillatory member, an electromagiet and its armature, the armature being adapted when attracted to operate said oscillatory n'ieinber, and means independent, of the magneHfmr moving the armature thereof laterally to position the same for moving the oscillatory member alternately in opposite directions.
